Abstract

The present invention provides a method for producing an eye makeup cosmetic composition comprising an acrylate-based copolymer and a cosmetic using the same.

Description

The present invention relates to an eye make-up cosmetic composition comprising an acrylate-based copolymer,

The present invention relates to an eye makeup cosmetic composition.

Eye make-up cosmetics include, for example, shadows, liners, and mascaras.

The eye shadow make-up composition is broadly classified into powder, cream, liquid and the like according to the formulation. The eyeliner is classified into a liquid eyeliner, a brush pen eyeliner, a pencil eyeliner, and a gel eyeliner depending on the container and the formulation. Mascara is divided into volume, curling, and lash according to the cosmetic effect, and it is classified into a fixer and a broker according to the application.

A carbon black pigment is generally used to make an eyeliner composition having a high blackness. However, carbon black is characterized by high gloss. Thus, silica particles are mainly used to lower the gloss to produce a low gloss eyeliner composition. However, there is a problem that silica particles having a large particle size are not ejected from the brush pen eyeliner among the eye makeup products.

Accordingly, there is a growing need to develop an eye makeup cosmetic composition which is low in gloss and capable of producing natural eye makeup.

It is an object of the present invention to provide an eye makeup cosmetic composition exhibiting a cosmetic effect with a low gloss.

An embodiment of the present invention provides an eye makeup cosmetic composition comprising an acrylate-based copolymer having a glass transition temperature of 80 to 120 占 폚.

The cosmetic composition of the present invention may contain 2 to 25% by weight of an acrylate-based copolymer.

The acrylate-based copolymer may have an average particle diameter of 0.5 to 3 탆.

In addition, the eye makeup cosmetic composition of the present invention may further comprise at least one member selected from the group consisting of polyols, preservatives, surfactants, oils, waxes, pigments and purified water.

Another embodiment of the present invention provides an eye makeup cosmetic comprising the above cosmetic composition. Preferably, the cosmetic is a brush pen eyeliner.

Yet another embodiment of the present invention is a method for preparing a coloring agent, comprising the steps of: a) mixing and stirring a pigment on an aqueous phase; And b) mixing and stirring an acrylate-based copolymer as a film former on the water.

The water phase of the step a) may include at least one selected from the group consisting of a polyol, an antiseptic, a surfactant and purified water.

The present invention relates to an eye makeup cosmetic composition comprising an acrylate-based copolymer, and can achieve a matt cosmetic effect with a low gloss.

Further, since the cosmetic composition of the present invention can be easily discharged from any container, it can be applied to various formulations.

The acrylate-based copolymer may have an average particle diameter of 0.5 to 3 탆, preferably 0.7 to 2.5 탆, more preferably 1 to 2 탆. If the average particle diameter of the copolymer is less than 0.5 占 퐉, the effect of reducing the gloss is insignificant. If the average particle diameter exceeds 3 占 퐉, the feeling of use in the cosmetic effect may be lowered due to the particle size.

The glass transition temperature of the acrylate-based copolymer is not particularly limited, but is preferably 80 to 120 ° C, 85 to 120 ° C, 90 to 120 ° C, 95 to 120 ° C, 100 to 120 ° C, 105 to 120 ° C, 80 to 110 ° C, 85 to 110 ° C, 90 to 110 ° C, 95 to 110 ° C, 100 to 110 ° C, 80 to 105 ° C, 85 to 105 ° C, 90 to 105 ° C, 95 to 105 ° C, , 80 to 100 ° C, 85 to 100 ° C, 90 to 100 ° C and 95 to 100 ° C, and when it is less than 80 ° C, the gloss of the eye makeup cosmetic composition is high, If the temperature is higher than 120 ° C, the skin may be covered with whitening whilst being dried upon application to the skin, which is not preferable.

In addition, the eye makeup cosmetic composition of the present invention may further comprise at least one member selected from the group consisting of polyols, preservatives, surfactants, oils, waxes, pigments and purified water.

In the present invention, the polyol may be a polymer compound having a hydroxyl group, for example, one or more substances selected from the group consisting of ethylene glycol, propylene glycol, glycerin, butylene glycol, and combinations thereof, It does not.

Preparation of Examples and Comparative Examples

In Examples 1 to 3 and Comparative Examples 1 and 2, each raw material was weighed in a beaker according to the contents and contents shown in Table 1 below, and then uniformly mixed at room temperature using a disper. The polyol, the dispersant, and the purified water were charged and uniformly mixed at 300 rpm for 5 minutes. The dye was then added and mixed uniformly at 500 rpm for 10 minutes. Then, an acrylate-based copolymer (styrene-acrylate copolymer, average particle diameter: 1 to 2 탆, Tg = 95 to 110 캜) was added as a film forming agent and mixed at 800 rpm for 30 minutes. The bubbles were removed and each cosmetic composition was prepared.

Table 1 below shows the components and contents of the cosmetic compositions of Examples 1 to 3 and Comparative Example 1.

EXPERIMENTAL EXAMPLE 2 Evaluation of feeling and cosmetic effect

Experiments were conducted to evaluate the feeling of use of the compositions prepared in Examples 1 to 3 and Comparative Examples 2 to 3.

The feeling of use was determined by comparing the effects of the products of Examples 1 to 3 and Comparative Examples 2 and 3 to 20 consumers of 20 to 30 years old women. After rating each item, a score of 0 to 5 was given The scores were averaged. The results are shown in Table 4 below.
